尼古拉地图的普遍形式

Universal form of the Nicolai map

Olaf Lechtenfeld, Maximilian Rupprecht

摘要:

在整体超对称理论中,将所有的反对易变量和辅助变量积分出去,得到非定域玻色子理论,并用Nicolai映射刻画了它。后者是由一个耦合流泛函微分算子产生的,当超对称性在壳外实现时,该算子可以正则地构造。给定任何标量超场理论,我们提出了一个普遍的公式,尼古拉映射和它的逆积分耦合流算子的有序指数。我们证明了我们的公式也适用于超对称规范理论。

英文摘要:

The nonlocal bosonic theory obtained from integrating out all anticommuting and auxiliary variables in a globally supersymmetric theory is characterized by the Nicolai map. The latter is generated by a coupling flow functional differential operator, which can be canonically constructed when the supersymmetry is realized off-shell. Given any scalar superfield theory, we present a universal formula for both the Nicolai map and its inverse in terms of an ordered exponential of the integrated coupling flow operator. We demonstrate that our formula also holds for supersymmetric gauge theories.
